Using relations in a right triangle, it is found that the approximate measure of angle ACB is of 53.1º.
What are the relations in a right triangle?
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
In this problem:
- The length of the side adjacent to angle C is of 15 cm.
- The hypotenuse is of 25 cm.
Hence:
[tex]\cos{C} = \frac{15}{25}[/tex]
[tex]C = \cos^{-1}{\frac{15}{25}\left(\right)}[/tex]
[tex]C = 53.1[/tex]
The approximate measure of angle ACB is of 53.1º.
